    ABSTRACT: Understanding inbreeding in cassava can guide breeders to explore its effects. Therefore, the aim of this study was to evaluate the effects of inbreeding depression in cassava, as well as to select transgressive individuals. Five elite cassava varieties were self-pollinated (Cascuda, BRS Formosa, Fécula Branca, Mani-Branca, and BRS Mulatinha), and the S1 families were evaluated in an augmented block design with six repetitions. The traits evaluated were fresh root yield (RoYi), above ground yield (AGYi), starch yield (StYi), harvest index (HI), dry matter content (DMC), and plant height (PlHe). The inbreeding depression varied widely between families; it was high in BRS Formosa, with averages of 19.38 % (RoYi), 1.68 % (AGYi), 18.18 % (HI), 0.47 % (DMC), 17.54 % (StYi) and 3.5 % (PlHe). Except for the S1 family of BRS Formosa, the additive effects (μ + α) were the most important, ranging from 69.95 % (RoYi) to 98.20 % (AGYi). In contrast, the contribution of heterozygous loci (δ) was most relevant to RoYi, HI, and StYi, with averages of 30.05, 23.07, and 27.82 %, respectively, although these effects were more pronounced in S1 derived from BRS Formosa and Mani-Branca. Therefore, the exploitation of inbreeding effects in cassava can contribute to the selection of plants with better agronomic performance in order to obtain cassava inbred with high genetic and agronomic potential for use per se or as parents to produce new hybrids.

    ABSTRACT: Fusarium root rot caused by Fusarium solani f. sp. pisi (Fsp) can result in major yield losses in pea (Pisum sativum L.). Currently no fungicides effectively manage this disease. Previous studies evaluated the Pisum germplasm collection for resistance to Fsp, however, evaluations of commercial market classes of pea cultivars grown in the US, and elsewhere, have not been reported. This study evaluated pea accessions and commercial cultivars for Fsp resistance under greenhouse conditions. Accessions evaluated included pigmented lines with high levels of partial resistance to Fsp. Based on root disease severity (RDS) values, the most Fsp-resistant Austrian winter, green fresh, green dry, yellow dry, green winter and yellow winter pea were: PI 125673, 5003, ‘Banner’, ‘Carneval’, PS 05300234, and ‘Whistler’, respectively. Genotypes with a RDS value of 3.05, on a 0–6 scale with 6 being severe, or less had no significant (P ≤ 0.05) reductions in plant height, shoot dry weight, and root dry weight, compared to non-inoculated controls, establishing an important disease threshold value for pea breeders. Plant height, more than shoot dry weight or root dry weight, was the most highly negatively correlated growth parameter related to RDS in repeated tests based on Pearson’s Correlation coefficients. However, root dry weight was also a highly sensitive growth parameter affected by Fsp since 14 of 33 genotypes had significant (P ≤ 0.05) reductions in root dry weight compared to non-inoculated controls, while only 5 of 33 genotypes had significant reductions in plant height and/or shoot dry weight in combined tests.

    ABSTRACT: Whole-genome duplication (polyploidy) occurs frequently and repeatedly within species of plants. According to the source of the genomes giving origin to a polyploid plant species, these are classified into allopolyploid (when two or more genomes are combined through either intraspecific or interspecific hybridization) and autopolyploid (when a single genome becomes duplicated). According to the time period in which polyploidy occurred plant species are classified as paleopolyploid (ancient polyploids), mesopolyploid (less ancient polyploids), and neopolyploid (recent polyploids). Many plant species appearing as diploid are actually paleopolyploids (ancient polyploids) derived from at least one event of whole-genome duplication followed by a process known as diploidization, which consists in massive gene loss and genomic reorganization (diploidized paleopolyploids). Many polyploid species of plants have been shown to present morphological and physiological characteristics making them further attractive for industry than their lower ploidy level counterparts. Polyploidy is a fundamental but relatively underexplored biological process. With the aim of understanding the factors involved in the formation of polyploid plant species, many studies have been carried out on synthetic polyploidy obtained by mitotic inhibitors and hybridization. However, the rapid progress of genetic engineering techniques makes genetic modification (GM) to become a feasible strategy for obtaining polyploid plants. In this review we discuss advances made about factors known to influence plant polyploidy and we suggest that in a future, this knowledge could be used for generating polyploids in vitro by GM and for crop improvement.

    ABSTRACT: Transgenic switchgrass (Panicum virgatum L.) has been produced for improved cell walls for biofuels. For instance, downregulated caffeic acid 3-O-methyltransferase (COMT) switchgrass produced significantly more biomass and biofuel than the non-transgenic progenitor line. In the present study we sought to further improve biomass characteristics by crossing the downregulated COMT T1 lines with high-yielding switchgrass accessions in two genetic backgrounds (‘Alamo’ and ‘Kanlow’). Crosses and T2 progeny analyses were made under greenhouse conditions to assess maternal effects, plant morphology and yield, and cell wall traits. Female parent type influenced morphology, but had no effect on cell wall traits. T2 hybrids produced with T1 COMT-downregulated switchgrass as the female parent were taller, produced more tillers, and produced 63 % more biomass compared with those produced using the field selected accession as the female parent. Transgene status (presence or absence of transgene) influenced both growth and cell wall traits. T2 transgenic hybrids were 7 % shorter 80 days after sowing and produced 43 % less biomass than non-transgenic null-segregant hybrids. Cell wall-related differences included lower lignin content, reduced syringyl-to-guaiacyl (S/G) lignin monomer ratio, and a 12 % increase in total sugar release in the T2 transgenic hybrids compared to non-transgenic null segregants. This is the first study to evaluate the feasibility of transferring the low-recalcitrance traits associated with a transgenic switchgrass line into high-yielding field varieties in an attempt to improve growth-related traits. Our results provide insights into the possible improvement of switchgrass productivity via biotechnology paired with plant breeding.

    ABSTRACT: Common cutworm (CCW; Spodoptera litura Fabricius) is a major leaf-eating insect that affects soybean crops in central and southern China. Understanding CCW-associated traits in soybean will provide insights for improved breeding strategies for resistance. The purpose of this study was to explore the genetic mechanisms underlying resistance to CCW. In this study, one natural population consisting of 219 soybean landraces from a wide geographic range was employed. Three traits, namely larval weight (LW), duration of larval stage (DLS) and pupal weight (PW) were evaluated as indicators for CCW resistance. Using 1536 single nucleotide polymorphisms (SNPs), a genome-wide association analysis was conducted to identify genomic regions associated with LW, DLS and PW in this natural population. Seven SNP-trait associations were identified using a mixed linear model (MLM). Four SNPs were co-associated with two traits. Three loci were significantly associated with CCW-resistance. Most of the detected loci were located within genomic regions previously identified as quantitative trait loci (QTLs) for these traits. The region on chromosome 6, which co-associated with LW and DLS, included several QTLs for reaction to disease or insect, such as Fusarium virguliforme, corn earworm and bean pyralid. On chromosome 7, two SNPs have been reported to associate with CCW, corn earworms, soybean aphid and bean pyralid moth infestations. Two putative genes (MYC2-like and JAM2-like) on chromosome 7 that may be associated with resistance to CCW were identified. These markers, located in previously reported QTLs, are consistent with previous findings and may represent important targets for the identification of CCW resistance-related genes. These results may provide a profound understanding of the genetic basis for resistance to CCW in soybean and the foundation for resistance to biotic stress through marker-assisted selection breeding strategies for CCW.

    ABSTRACT: When developed, perennial grain sorghum could provide an opportunity for more ecologically sound food production. In 2002, we initiated a perennial sorghum breeding program, using Sorghum bicolor (L.) Moench × S. halepense (L.) Pers. populations. In 2011–2013, we evaluated 27 breeding lines from three stages of the program in field experiments to estimate response to selection during the program’s first 7 years for perenniality and more domesticated phenotype. Regression analysis of mean grain yield and single-grain weight on breeding cycle (0, 1, 2) indicated a significant increase in each of the seeded experiments and for means over all years. For winter survival index, the regression coefficient was small but significant and negative in 2011, while non-significant in 2012. Grain yield was not significantly correlated with survival index, while single grain weight was significant and negatively correlated with survival index, with r = −0.4923. We conclude that combined selection for perenniality, a more domesticated phenotype, adaptation, greater grain size, and higher grain yield can result in progress in breeding perennial sorghum.

    ABSTRACT: To create recombinant substitution lines from chromosome arm substitution lines (CASLs) of wild emmer, the common wheat cultivar ‘Bethlehem’ (BLH) was crossed with 4 CASLs of group 1 and the resulting F1s were backcrossed with corresponding BLH ditelosomic (DT) lines to produce monotelosomic plants (BC1F1, 2n = 6x = 41 + t). For each cross combination, about 100 BC1F2 plants derived from 47 to 49 BC1F1 plants were analyzed for their chromosome number and constitution. The frequencies of plants with 42 or 41 + t chromosomes in [DT1BS × (BLH × CASL1BL)] progenies were much lower than in crosses involving CASLs 1AS, 1AL and 1BS; while the frequency of [DT1BS × (BLH × CASL1BL)] progeny plants with 41 chromosomes was high. A total of 49 (BLH × CASL1BL) BC1F1 plants could be clearly classified into three types based on chromosome constitution of their 461 BC1F2 progenies. In type I (21 BC1F1 plants), 95 % of BC1F2 plants possessed 42 chromosomes (counting the telosomic chromosome as an entire chromosome). In type III (24 BC1F1 plants), most BC1F2 plants (75.6 %) had 41 chromosomes and no telosomic chromosome. In type II (4 BC1F1 plants), the expected number of ~48 % of BC1F2 plants had the telosomic chromosome, but about 70 % had fewer than the expected 42 chromosomes. All type III BC1F1 plants were confirmed to have experienced elimination of telosomic chromosome 1BS. Observation of BC1F1 seedling mitosis revealed that the elimination of 1BS occurred most probably during embryogenesis. However, type II BC1F1 plants experienced the elimination of different chromosomes, which was deduced to occur during meiosis. Reciprocal crosses indicated that both types of chromosome elimination occurred only when BLH DT1BS, which has Chinese Spring cytoplasm, was used as female parent. Collectively, these results reveal a genetic system on chromosome arm 1BL of wild emmer that interacts with the CS cytoplasm to cause chromosome elimination.

    ABSTRACT: Genomic selection studies usually use few environmental models to predict progenies from biparental crosses. However, in a maize breeding program, numerous crosses need to be evaluated in multiple field trials to identify single-crosses with greater yield potential. In this study, 614 AFLP marker effects estimated in 250 maize single-crosses evaluated in 13 environments were used to assess the influence of training population size (N), number of markers (NM), genotype-by-environment interaction (G × E) and population structure on the prediction accuracy (rMG) for grain yield using RR-BLUP model. Cross validation analysis were performed within and across environments, and within and across groups of related single-crosses. Then, genomic selection was compared to phenotypic selection in identifying the best single-crosses in a maize breeding program scheme. In general, increasing the training population size and the number of markers did not led to higher accuracy estimates. Predicted accuracies from cross validation analysis within environments were significantly higher than between environments, indicating that the effect of G × E interaction was important. Accuracy estimates were also higher when training and validation sets were composed of related single-crosses. In all scenarios, wide intervals of accuracy were found, meaning that genomic prediction may not be effective depending on the single-crosses sampled. The use of genomic prediction in maize breeding programs was discussed emphasizing the need of a training set evaluated in multiple environments and designing a genomic selection experiment according to the population structure so as to reduce sample problems and maximize the accuracy and the success of prediction.

    ABSTRACT: Three-year field assessment of gene flow from the genetically modified herbicide-resistant spring wheat variety ‘Andros’ to its non-transgenic counterpart has been conducted. A circular field trial design where the wheat plants containing the bar and gfp genes were planted in a central plot, while the recipient non-transgenic plants were grown in eight compass sectors at a distance of 1–5 m from the pollen source, has been developed. Gene flow was analyzed by testing the glufosinate-based herbicide resistance in seedling progeny. The phenotypic and molecular examination of more than 712,000 germinated seeds allowed us to draw a conclusion that the pollen-mediated transgene flow might occur at a low frequency (<0.8 %) even if the nontransgenic wheat was located in the proximity to its transgenic counterpart. The strong asymmetric distribution of gene flow and the maximum outcrossing rate were detected in compass sectors following the direction of the dominant wind. The gene flow rate averaged over all wind direction varied in different years from 0.134 to 0.416 %. The dramatic reduction in transgene flow frequencies was observed while increasing the distance between transgenic and non-transgenic plots. The rise of average gene flow due to significant increase of the transgene pollen area was not confirmed statistically. These results predict that the pollen-mediated transgene flow in spring wheat can be maintained at negligible levels while the existence of a short isolation distance in order to prevent contamination of adjacent non-GM wheat.

    ABSTRACT: Papaya (Carica papaya L.) is a major fruit crop in the tropics and is a model system for studying sex chromosome evolution in plants. From a simple sequence repeat (SSR) mapping project in papaya, 37 SSRs displayed non-parental alleles in the F2 population, known as off-type markers. They all belong to Class I (≥20 bp, hypervariable markers). To investigate the molecular basis of these non-parental alleles, seven SSRs with off-type alleles were cloned and sequenced from two parents and selected F2 individuals. SSR repeat motif variation was the major cause for the generation of off-type alleles and single nucleotide polymorphisms (SNPs) and Insertion/deletion also contributed to off-type polymorphism. Off-type SSRs arose after one meiosis at 3 % frequency. Two of the seven markers had no polymorphisms between the parents but non-parental alleles segregated among the F2 individuals. Four of the seven markers exhibited SNPs between parents with transition and transversion at 2:1 ratio. Six markers showed additional SNPs between F2 offspring and parents with transition and transversion at about 1:1 ratio, suggesting higher than expected level of transversion mutations at the F2 population after one meiosis event between the parental genomes. These off-type SSRs were analyzed in a second F2 population and 43 % of them were conserved. The major cause of off-type SSRs in papaya is the variation of repeat length in Type I SSRs, and the underlining mechanism might be DNA replication slippage of repeat motifs. The presence and high conservation of these off-type markers demonstrated that hypervariable class I SSRs could generate genetic variation in one generation and increase genetic diversity for natural selection to enhance fitness.
